How bad of an idea is this mounting my carter fuel pump infront of the radiator... Me and my grandpa were looking at where to mount the aftermarket fuel pump there really did not seem to be enough room to mount it where the stock pump was. My grandpa thinks it would be better off running fuel lines all the way to the front of the radiator. I thought that fuel pumps need to be a certain distance away from the fuel tank... Whats your guys input on this???

there is enough space to mount the carter fuel pump near or around the stock location. just get creative with it.

It will probably work but less than ideal. The pump is better closer to the tank to handle rapid throttle opening, and to minimze the work required to draw the fuel from the tank to the pump. Read the Carter installation instructions for their recommendations.

In fact there is plenty of room where the stock pump goes. Remove the stock pump, filter, and mounting plate. The bracket that comes with the Carter pump fits nicely a few inches to the inside of the unibody channel, just above where the stock pump was. There were some pics on this site at one point. You will need some angled brass fittings to be able to connect the output fuel line to the pump.

I have seen pictures of it there im just not really sure how it was done, it looks like it would be a big pain in the *** to actually get it in there. There is a spot on the frame rail but there would be no way to get a nut on the other side of it...

very bad.

do you have other pictures showing how you mounted it, the section it appears you have it mounted on is at a strong slant on my car... Do you have the top bolts of the mount (next to where the fuel pump attaches to) connected or did you attach it by using the bolts out the side? How did you mount it on the other side? Pull out the bins or what?

Thanks

anyone else know how that cdrad51 mounted it like this? You don't have any more pictures showing how its mounted do you?

I found this pic in another one of cdrads posts:



Also, I am currently doing the exact same thing as you..and was pondering if i could put the pump in the engine bay. But, I guess it will work a lot better closer to the tank..so gotta figure out how to mount it tomorrow.

it's probably not too good an idea. I remember from my fluids class that you can only use vacuum to suck a liquid for a specific amount of distance before the fluids start to boil, plus, it's gonna be more effective if it's pushing the liquid rather than pulling it.

Warning warning warning. Do not mount your pump in or anywhere near the engine bay. The pump is designed to push not pull. The intial prime is because it is below the tank, then it can build pressure and deliver the psi and volume that it was designed to do. Putting it up front will cause it not only to pull but push resulting in premature failure of the pump and poor overall delivery. :

ok, so now I just need more details on how its mounted, its not really clear with cdrad51's pictures as to what bolts he has holding it on..

You can mount it straight to the frame rail using self tapping sheetmetal screws.

Which will be to the left and a little bit below where you see the pump mounted in the above pics..

cdrad51

I used the upper right hole in the pump mount I think. Or maybe the lower right. I didn't even have to drill a hole - I used the bolt that holds the brake line holder in place. See where the brake lines are running? anyways, I think you can figure it out from there.

Making a fuel pump draw rather than push fuel is a good way to heat fuel - which is bad. Running more lines through a hot engine bay is similarely bad. And mounting a fuel pump up in the crumple zone of a car so you can go boom ahhh ahh it hurts [dead] in the event of a minor fender bender is also - say it with me now - bad.

That said, good on ya for thinking outside the box and wanting to try something new. IMHO your initial idea was a bad (sorry) one, but coming up with ideas is good.

Dude, it took me about an hour if that to install mine similar to where his is on the back of the storage bin. Its not hard AT ALL.

Take the screws out from around the storage bin and pull it out. Take your bracket for your pump and mark the three mounting holes (making sure theres nothing behind on the backside of the bin). Take a drill and drill them out. Now lay your pump bracket on the ground so that it makes a peak (the right angle facing up). Smack it with a hammer to "open up" the angle some so that when you mount it on the slanted bin, the pump will still hang level (this isnt even really necessary, but it wont hurt). Take the bracket and put it on the back side of the bin under the car, put the bolts through and the nuts and washers on. Mount the pump to the backet. Plumb your lines. Voila.

ok, thanks alot guys, it was my grandpas idea to mount it up front and the whole time I thought it was a bad idea, but you guys brought up some really good points with it heating up the fuel, the pump designed for pushing not pulling and in case of an accident...

Thanks alot!

I have a Holley Blue I just installed and mounted it in almost the very same spot as cdrad put his Carter. Seems to be working fine, and the constant buzzing tells me it's working. It's every bit as loud as everyone said it would be.

Now I just need to wire it up better. Running the window up and down changes the tone of the buzzing.

Why do so many people insist on mounting the pump on the flimsy sheet metal when there's a perfect spot on the frame rail just waiting to be used? It's so easy with the Carter. All you have to do is drill a few holes and use the big self tapping screws provided.

cdrad51

Where exactly? I initially was planning to use the rail but when I got down there, couldn't find a spot that would leave the pump in a vertical position.

that how I did my carter. With the MSD F/I fuel pump, it is sitting on an aluminum plate which is similar to the stocker.

Personally, I would not use sheet metal screws for mounting anything that vibrates. I would recommend a more positive locking fastener like cap screws with nylock nuts or at least spring washers or Locktite. Sheet metal screws will likely come loose over time and then the pump will hang down or worse fall down and hit the ground.

The aluminum plate is the answer...now a big show of hands from the Carter fuel pump crowd who have had the poor pump actually fall off from using the sheetmetal screws in the kit. Let's kill this urban legend right now before it gets legs if it just ain't true....

But if it is true....well, you didn't want that noisy, pulsing, old tech Carter anyway, right?..

Don't make me pull out the pic again...

cdrad51

NOOOOOOOOOOOOOOOOO... not that pic AGAIN!
